UNITED' STATES vParrain* ort- Ica LOAN IF. DOEN, OE CLEVELAND, OHIO,`ASS IGNOR THE CLEVELAND HEATER COM- PANY, OF CLEVELAND, OHIO', v.A CORPORATION OF OHIO VALVED COUPLING Application nled April 15,

This invention relates to gas burning appliances and in particular the means for regulatng and controlling the source of supplyto the appliance.

It has for its object the provision of a shutoi valve-that may be readily and easily. secured to and detached from the appliance.

Another object of. this invention is to provide a shut-ofvalve in which the outlet orifice may be independentlyadjusted to take care of the various kinds of gas and diierent he heating burners of this invention is to roliances W ich the appliance from the gas supply line and that does not necessitate turning oi thevgas at the meter when such disconnection is made.`

A further object of ,this invention is to provide a valve in which the inlet and-outlet portions of the valve are .detachably secured to each other.

Prior to my invention it has been the usual practice to secure to the mixing or Venturi tube of the gas burner without theinterposition of any con- Another object of vide a valve for gas burning ap venient means for disconnectin the gas con,.

v duit from the burner. It is o ten desirable and necessary in 'as burning appliances to remove the burner or cleaning and other purposes. Such removal of the burner may read-A ily and easily be accomplished with my improved valve, by .simply unscrewing the union f nut 5 from the valve body, which serves to disconnect the burner from the gasv supply line.

In the drawing Figure 1 is a sectional elevation of my improved valve.

Figure 1.

Figure 2 is an enlarged elevation partly in section of the adjusting needle. A Figure 3 is a section taken on line 33,

The valve shown in the drawing comprises a valve body 1 havingan inlet opening.' 2 threaded toreceive a` pipe to be connected;

lto the source of gas supply and having an externally threaded outlet 3 to receive the union nut 5 which provides a means for dethe iow of gas from- 1a spud 7, provided with valves of the type shown 1927. serial no. 184,141.v

taxiably securing the nipple 4 to the valve bo y. f

The nipple 4 is externally threaded to receive a spud carrier .6 which in.turn receives an orifice 8. The

Spud carrier 6 is externally threaded for se- Y curement to the applicance upon which it is used. The locknut 9 provides a means for lockingl the `spud carrler to the appliance. The nipple 4 is internally threaded to receive the adjusting needle 10.

Referring to theenlarged view of the needle 10, shown in Figures 2 and 3 itv will be seen thatthe needle has a threaded portion I22 at one end by which it is adjustably carried in the nipple 4. The opposite end27 ofthe needle 10 is conical in shape for reception in the orifice 8 ofthe spudy 7 and provides a means of Ivarying the size of the openingof the orifice 8. The needle 10 is further pro vided with longitudinal recesses 23, which permit the flow of gas throu h the nipple 4.

A hole 24 is drilled throng the adjustingl needle 10 intersecting the vinner'terminus of the axially' drilled hole 25 rovided'in the conical end of the needle. and 25 provide a minimum fixed opening for gas to be supplied to the burner when the conical end 27 of the needle 10 is in contact with the spud 7 at the margin,` of the orifice 8. The size of the holes 24 .and'25 is determined by the size of the burner with which the valve is to be used.

he openings 24 vleo With a given burner the'vv passages 24 and 25 are of such size that when the gas supply is wholly under their control, the burner. will receive the proper amount of the highest grade 'natural gas at the maximum pressures which may be anticipated, for its operation at maximum eiiiciency.

vThe orifice 8 of thespud 7V is designed to in a valve of this type and any desired adjustment between these two extremes may be Y obtained by moving the needle toward or away yfrom the orifice 8.

Heretofore the usual practice has been to use spuds havin larger or smaller orifices Vto take care of t e various types of gas and Y gas pressures. .Thus a gasburning appliancev at'any 'ordinary pressure that maybe encountered by reason of the large orifice 8 and thevrelativelysmall orifice Q5 and the adjustments that may be' effected between these two limiting orifice sizes.

Furthermore, it yis to beV understood that 'the particular forms of apparatus shown and described and the particular procedure set forth are presented for purposes of explanation and illustration and that various modiications of said forms and procedure can be made without. departing from my invention as defined in the appended claims.

I claim:
